of any accumulation of gasolene or other liquid, so that in the event thatrthe nozzle discharges more fluid than is vaporized none of this excess will be carried into the engine but such excess will all return to the reservoir.

ln operation, Whenever air drawn inv through the inlet 8, the gasolene is drawn up through the nozzle 6 and blown against the deiectorwhich breaks up -the stream of gasolene and discharges it downward oli the edge of the dellector in a fine 'spray into the current of air which is accellerated in speed in passing through the contracted throat below the de'lector, and thus the gasolene is intimately mixed with the air and etiectually vaporized, any unvaporized excess going baolento the reservoir as heretofore explained. The diluting air coming in through the openings 13 in the sise of the mixing chamber, strikes the side ot the upper part ll of the airytube and is thus broken up and discharged upward and in- I,Ward from the upper and conical end of said tube, and thus becomes intimately mixed with the carbureted air discharged from the tube, and whenever the throttle is shifted to increase or decrease the flow through the device, the sleeve 19 is correspondingiy shifted to simultaneously increase or decrease the quantity 'ot air admitted through the openings 12% whereby the richness of the mixture is kept substantially uniform, regardless of the quantity required by the engine to do its work. By adjusting the outer sleeve 2l to more or less throttle the inlet of the diluting air, the

normal richness of the charges may be modified at pleasure.

What claim ist 1. A carburetor, comprising an upwardly projecting air passage, means for admitting a mixture of liquid fuel and air to said passage, a mixing chamber surrounding the upper end of said passage and extending above the same, a. throttle in the upper part of said chamber, lateral openings in the side of said chamber opposite the air passage, a sleeve rotative about the mixing chamber and having corresponding openings to control the admission of air, and gearing c0nnecting the throttle and sleeve whereby the sleeve may be rotated on the mixing charnber as an axis, and the throttle valve simultaneously operated.

2, A carnureter, comprising an air passage, ineens for supplying a mixture of air and liquid fuel to said passage, a mixing chamber surrounding the upper end of the passage and extending above the same, a throttle in the upper part of said chamber, said chamber also having air inlet openings opposite said passage, an inner sleeve having corresponding openings and rotative about the chamber, gearing connecting the throttle and the sleeve to simultaneously operate the same,A and an outer sleeve also having corresponding openings and independently rotative about the inner sleeve, a

spring to move the outer sleeve to open position and an arm on the sleeve to manually move the sleeve to closed position.
